Our Staff
Silvi Sullivan, B.S.N., M.A.T., M.Ed.


Hello! I'm Silvi, the Director of Water of Life Lutheran School. I’m thrilled to be a part of this wonderful ministry; it's a combination of my greatest passions- educating children and sharing the love of our gracious Savior.

Ministry work has been a part of my life 20 years. I have served the church in many different ways, everything from church program development, and Sunday School Assistant Superintendent, to Sunday School teacher and Youth Group leader.


I've been involved in education for almost 20 years. I have a Bachelor of Science in Nursing, a Master of Arts in Teaching, and a Master of Education in Early Childhood Education. I'm a member of the National Association for the Education of Young Children (NAEYC) and the Lutheran Education Association (LEA). I enjoy spending time with family, cross-stitch, cooking, hiking, reading, and movies. But most of all, I love being an educator. 


I've raised two daughters and have had a wide variety of life experiences: pediatric nurse, traveling extensively, living in every part of the country as well as overseas, and owning a business, among others. I'm also bilingual (German). So, I understand and appreciate the challenges facing today's families; I'm here for you and your children.


At Water of Life Lutheran School, we care deeply about a most precious treasure, your children. We're profoundly committed to the spiritual and emotional nurturing they'll receive here; to help them grow in their understanding of the God who loves them. We’re also committed to their intellectual and physical growth. It's our goal to help each and every child realize their potential, and find joy in the discovery and learning process!


Please feel free to contact me anytime with your questions or concerns!
